A39 A uniform rod AB of weight W and which is 20 cm long is suspended by two vertical springs X and Y attached to the rod at A and B respectively. The upper ends of the springs are attached tó a horizontal beam. When the springs are unextended they' have the same length. The tension Tg in X'is given by Tx = kx and the tension Ty in Y is given by Ty 3ky, where kisa constant and x and y are the extensions of Xand Y respectively. At what distance from A must a body of weight 5Wbe attached to the rod if the rod is to be horizontal?

A39 A uniform rod AB of weight W and which is
20 cm long is suspended by two vertical
springs X and Y attached to the rod at A and
B respectively. The upper ends of the springs
are attached tó a horizontal beam. When the
springs are unextended they have the same
length. The tension Tg in X'is given by
Tx = kx and the tension Ty in Y is given by
Ty 3ky, where kis a constant and x and y are
the extensions ofX and Y respectively. At what
distance from A must a body of weight 5W'be
attached to the rod if the rod is to be
horizontal?
